New 512GB Device Brings the Higher Bit Density of QLC to UFS
TOKYO--BUSINESS WIRE--
Kioxia Corporation, a world leader in memory solutions,today announced that it has begun mass production of the industry's first1 Universal Flash Storage (UFS)2 Ver. 4.0 embedded flash memory devices with 4-bit-per-cell, quadruple-level cell (QLC) technology.

Notes
(1)Industry first claim based on Kioxia survey of publicly available information as of October 30, 2024
(2)Universal Flash Storage (UFS) is a product category for a class of embedded memory products built to the JEDEC UFS standard specification. Due to its serial interface, UFS supports full duplexing, which enables both concurrent reading and writing between the host processor and UFS device.
(3)Kioxia Corporation's first sample shipment, as of February 8, 2013. https://www.kioxia.com/en-jp/business/news/2013/20130208-1.html
(4)PWM-G1 communication speed depends on the host and the device.
*In every mention of a Kioxia product: Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application. For details, please refer to applicable product specifications. The definition of 1KB = 2^10 bytes = 1,024 bytes. The definition of 1Gb = 2^30 bits = 1,073,741,824 bits. The definition of 1GB = 2^30 bytes = 1,073,741,824 bytes. 1Tb = 2^40 bits = 1,099,511,627,776 bits.
*1 Gbps is calculated as 1,000,000,000 bits/s. Read and write speeds are the best values obtained in a specific test environment at Kioxia and Kioxia warrants neither read nor write speeds in individual devices. Read and write speed may vary depending on device used and file size read or written.
